Smooth, Silent & Reliable Mobility for Medical Equipment
The 120mm (5-inch) 75mm(3 inch)  100mm(4 inch) medical twin wheel caster is designed for hospital beds, medical carts, patient transfer equipment, mobility devices, and healthcare furniture requiring smooth movement, quiet rolling, and high durability.
Manufactured with a high-strength nylon (PA6) frame and ultra-silent TPU tread, this caster delivers excellent shock absorption, low rolling resistance, and long-term reliability in demanding healthcare environments.

Why Choose Our Premium Stem Casters?

🏆 High-Load PA6 Nylon Structure: The main frame and wheel core are molded from premium polyamides (Nylon PA6). It provides exceptional structural rigidity, heavy load-bearing capacity, and maximum resistance to industrial oils, chemicals, and pharmaceuticals.
🤫 Ultra-Silent & Floor-Protective Treads: Featuring cutting-edge Elastomer technology (TPU for 75mm/100mm; TPE for 120mm). The treads offer a soft touch with high resilience, ensuring completely silent driving, superb fatigue resistance, and leaving zero streaks or scratches on expensive flooring.
🎯 Dual Precision Ball Bearings: Equipped with premium internal precision bearings that minimize friction. This allows effortless, smooth 360° swiveling and straight-line rolling even under maximum load capacity.
🛡️ All-Weather & Anti-Rust Performance: Designed with a rugged, rust-resistant threaded bolt and sealed housing, operating flawlessly in harsh environments from freezing -30°C up to scorching +80°C.

FAQs 

Q1: What is the difference between TPU and TPE treads on these casters?
A: Both materials offer industry-leading noise reduction and floor protection.

Our 75mm and 100mm models utilize premium TPU (Thermoplastic Polyurethane) for optimal wear resistance under concentrated loads.

The 120mm model incorporates high-grade TPE (Thermoplastic Elastomer), which maximizes shock absorption

and rolling smoothness for larger-diameter, heavy-duty applications.

Q2: Are these casters suitable for chemical and medical environments?
A: Yes. The main frame and core are built from Nylon (PA6), which provides outstanding chemical stability.

It is highly resistant to industrial oils, common detergents, alcohols, and pharmaceutical compounds,

ensuring a long lifecycle in hospitals and laboratories.

Q3: Do these wheels comply with international quality standards?
A: Absolutely. All three sizes (75mm, 100mm, 120mm) are strictly manufactured and certified under the EN12531 standard,

guaranteeing reliable load ratings, structural safety, and environmental compliance.
